SPECIFICATION forming part of Letters Patent No. 673,742, dated May 7, 1901.

Application filed March 9, 1900. Serial No. 8,089. (No model To all whom it may concern:

Be it known that I, JOSEPH ARTHUR WADE, a subject of the Queen of Great Britain and Ireland, residing at Liverpool, in the county of Lancaster, England, have invented an Improved Oombination-Tool, of which the following is a specification.

This invention has reference to a simple and inexpensive construction of combination hand-tool suitable for use as a ratchet-brace fol-drilling or tapping holes in confined places and also as a lifting appliance. The said tool comprises a body portion and a detachable reversible handle, the body portion being made in two parts, one of which is adapted to be connected to the drill or other device to be rotated and the other part to form an endwiseadjustable center for the first-mentioned part, and the handle which serves as a spanner being adapted to embrace the said body part and provided with a tooth or projection for engagement with one or other or both of two annular sets of teeth on the body part, whereby the latter can be turned in either direction at will.

Figure 1 shows in perspective the body part of a tool according to this invention. Fig. 2 is a similar view of the handle or spanner detached. Fig. 3 is a vertical section of the body part of the tool to an enlarged scale; and Figs. 4 and 5 are cross-sections on the lines A B and O D, respectively, of Fig. 3, showing the handle or spanner in reverse positions and having two teeth or projections suitable for a heavier tool, while Figs. 6 and 7 illustrate the form of spanner.

The body part a of the tool has its upper portion 1) octagonal in form, as illustrated in Figs. 1 and 5, and is formed with two circular collars c, that are formed with teeth d, the portion 6 between them being cylindrical in cross-section and equal in diameter to the distance between parallel sides of the octagonal portion 5 of the body part. The handle or spanner f is so formed that its jaws will fit the part b of the body portion of the tool and can be inserted between the collars 0 around the portion 6. The octagonal part b of the tool is bored and at its upper end is formed with internal screw-threads which receive a setting-up or feeding screw g, provided with a nut-like head it, and the lower end of the body at is suitably formed to receive the drill or screw-tap, which may be of square or other section so long as it is not able to rotate in the body part when the same is turned in either direction. The nut-like head it of the setting-up or feeding screw 9 is formed with a pointed projection t', and the part which is screw-threaded and enters the hole in the body part of the tool may be hollow, as shown in Figs. 4 and 5, if desired, to allow of the end of the drill or like tool ontering therein and being guided thereby.

The handlef has projecting on each side thereof at the junction of its two jawsj, which are longer than usual, so as to be more firmly supported between the two collars o, a pin or pins 7c, the length of which is such that it engages with the teeth of the two collars c. The pin 7c is formed somewhat like a ratchet tooth, for instance, with sides of which when the handle is fitted between the two collars one will be approximately radial to the axis of the part cand the other approximately tangential to said circular part and so that when handle or spanner is swung or oscillated about the part c in one direction the radial side of the pin or pins 76 will engage with the teeth d; but when the handle or spannor is swung or oscillated in the other direc tion it will become disengaged from the teeth d, owing to the tangential side of the pin or pins, causing the same to ride over the teeth d.

If the spanner is reversed or turned over, as shown in Fig. 5, the pins It. will engage the teeth cl and rotate the body part and drill when it is swung or oscillated in the opposite direction. The spanner is of such a size that the nut-like head h of the setting-up screw g or the uppor portion 1) of the body part a can be engaged by it for turning one of these parts relatively to the other for feeding the drill.

The body part of the drill-holder a, with the setting-up screw g, may be used as a lifting-jack, in which case the handle or spannerf may be used as a spanner for rotating either of thetwo parts while the other is held stationary.

It is evident that the body part a, fitted with a drill or other tool, can be more easily and truly placed in position when the handle is removed than can the ordinary ratchetbrace where the handle is fixed. Alsovthe present invention-has advantages over the ordinary ratchet-brace, which cannot be rotated in either direction without the addition of complicated parts.

What; I claim is- A hand-tool of the character described comprising a body portion having annular sets of identically formed and disposed teeth anda jecting ,teeth at opposite sides thereof the operating-surfaces of which are arranged radially and tangentially of said body portion,

whereby when the handle is reversed it is adapted to rotate the body portion in an opposite direction, substantially ,as. described.
